I am wondering is it possible to design a differential (or instrumentation) amplifier that will operate from single supply?
I have a 2Vp-p and 0.2Vp-p sine wave signals that need to go thru the differential amplifier. They both swing positive and negative.
But currently for this project I have only positive power supply. I can add an inverting converter if necessary but would like to know if I can reduce the costs.
If it is possible, could you please show an example.
